Is there still a imshow method for axes ?

Back with .86 I used to do lots of ax = axes() ax.imshow(M)

    > but in .87 this doesn't seem to work. It doesn't complain
    > but nothing happens. Simply calling imshow(M) does the job
    > however, but I thought the method call was nicer. Am I
    > missing something ?

works in svn...
